即時通訊工作ruby.railstutorial.org/ruby-on-rails-tutorial-book 。 即時通訊使用導軌3.2.7，叉勺，RSpec的，水豚，launchy和一些警衛:)使用規範進行測試，來自railstutorial第3章的水豚不起作用（have_selector（'title'，：：text =>'| Home'））
我在第3章與測試一個很奇怪的問題：
好像測試的arent工作是什麼在<head> -Tag內。如果我把<title> -tag放在<body> -tag裏面，而不是頭標籤，它可以正常工作。 它也適用於當我把<h1>-標籤<title>以上<head>-標籤。這很奇怪，不是嗎？
請幫我解決問題。
的示例是從：ruby.railstutorial.org/chapters/static-pages#code:title_test：
it "should have the right title" do
visit '/static_pages/home'
page.should have_selector('title',
:text => "Ruby on Rails Tutorial Sample App | Home")
end
誤差信息是：
Failures:
1) Static pages Home page should have the title 'Home' Failure/Error: page.should have_selector('title', :text => ' | Home') Capybara::ExpectationNotMet: expected to find css "title" with text " | Home" but there were no matches. Also found "", which matched the selector but not all filters. # ./spec/requests/static_pages_spec.rb:15:in `block (3 levels) in '
那一個是工作：
it "should have the h1 'Sample App'" do
visit '/static_pages/home'
page.should have_selector('h1', :text => 'Sample App')
end
呈現的HTML文件：
<!DOCTYPE html>
<html>
<head>
<title>Ruby on Rails Tutorial Sample App | Home</title>
<!-- some css,js stuff -->
</head>
<body>
<h1>Sample App</h1>
<p>
This is the home page for the
<a href="http://railstutorial.org/">Ruby on Rails Tutorial</a>
sample application
</p>
</body>
</html>
感謝
編輯： 你能找到的文件即時通訊與GitHub上的工作： https://github.com/farukg/sample_app/
鏈接到spec文件： https://github.com/farukg/sample_app/blob/master/spec/requests/static_pages_spec.rb
我所做的解釋： 主頁的代碼就像它應該是的。 關於頁面的代碼具有其自己的佈局，其中h1標籤位於title-tag之上，以顯示它適用於某種原因。 最後，幫助頁面的標題標籤也在其中起作用。
我絕對困惑，爲什麼我有這樣一個奇怪的行爲？

是的，當然，我也使用了save_and_open_page，這樣我就可以看到更改 – farukg 2012-07-30 17:37:57
